Ford Fiesta ST ECU Tuning by VR Tuned

The Ford Fiesta ST is one of the most epic hot hatches to ever come around. The tiny KP39 turbocharger provides insane amounts of torque, especially for a 1.6L engine. The torque combined with the brake-based torque vectoring system and suspension tuned specifically for autocross and canyon runs makes the Fiesta ST perfect for enthusiasts at any skill level. There are a couple of shortcomings with the Fiesta ST which revolve around the factory tune.

Ford did a pretty good job with the factory tune and really pushed the KP39 near its limits at 21psi, but issues like rev-hanging leave enthusiasts wanting more. Vivid Racing’s tuning division, VR Tuned, set out to develop a tune that improved drivability, horsepower, torque, eliminated rev-hang, and eliminated the limited torque in 1st/2nd gear.

VR Tuned played with the boost, ignition map, and fuel map until a happy medium between power and safety was found. The resulting tune put out 226hp (15% increase) and 242lb-ft (20% increase). The tune also eliminates the rev-hang which allows for much quicker shifting that is smooth. The increased torque really pulls the Fiesta ST out of tight corners and the increased horsepower helps it in the straights.
